Grand Slam of golf

Sponsor with the world's largest charity for orphans
The Grand Slam of golf consists of four major golfing events held each year; all four are recognized as a part of the world's two most prestigious tours, the PGA TOUR in the United States and the PGA European Tour. In order of their playing date, the events that make up golf's Grand Slam are:

  1. April - The Masters
  2. June - US Open
  3. July - The Open Championship
  4. August - PGA Championship

In December of each year since 1979, following these four major tournaments, the PGA of America holds a special two-day, 36-hole stroke-play competition exclusively for those players who have won one of the four major championships. This PGA Grand Slam of Golf tournament provides a prize of $1 million and initially was played at a different golf course each year. Since 1994, the Poipu Bay Golf Course on the Hawaiian island of Kauai has been the tournament's permanent home.
